Look at how Ruby does this: you provide an "attr=" method that is called on assignment, so you are not violating encapsulation or confusing behavior with state. It's sugar for a normal method call, which can have any behavior you want and mutates whatever state system it wants however it wants. I'm not saying that I want ->attr=$x, only that you are arguing against something that needn't be true. -- rjbsThread Previous | Thread Next
